What to Consider When Choosing the Best Key Finder

There’s no need to clutter your life with unnecessary gear. Instead, choose great gadgets that streamline your daily routine and reduce headaches. For folks who struggle to keep track of items big and small, key finders can be a game-changer. How do these little wireless devices work? Here are the basics you’ll need to know before purchasing.

Bluetooth vs. Radio Signal

Key finders work via an invisible signal that’s transmitted and received. One of two types of signal are used: Bluetooth or radio frequency (RF) waves. Bluetooth is a wireless technology that allows devices to exchange information over short distances (up to about 30 feet). By pairing a key finder with your smartphone via Bluetooth, items in close proximity can be found easily. Over longer distances (beyond 30 feet), your phone’s Wi-Fi network kicks in, and you can track lost belongings via an app, at ranges of 100 or more feet.

RF technology makes use of radio waves, which travel farther than Bluetooth but not as far as your Wi-Fi network. RF key finders cannot be paired with your smartphone. Instead, they come with a remote-control-like transmitter. This central transmitter keeps track of the small receivers attached to your gear. On the one hand, RF finders are easy to use. You won’t need a smart device, app, or Bluetooth technology. Just push a button and sound the alarm. On the other hand, key finders that utilize RF waves are only helpful up to distances of about 115 feet. This makes them perfect for at-home use. However, if you travel a lot or commute, Bluetooth-enabled key finders are probably more useful.

Size and Sound

Key finders need to be small enough to attach to a keychain but not so small that they’re easily misplaced themselves. Typically the tracking receivers that attach to keys and other items are between 1 and 2 inches long, 1 and 2 inches wide, and just a fraction of an inch deep. Their internal electronics contain ringers that go off when you press a button on the remote transmitter or via the app on your smartphone. For folks who are hard of hearing or simply desire the peace of mind that comes with a very loud alarm, look for loudness levels between 80 and 85 decibels. And be careful! Don’t operate one of these devices near someone’s head, as sounds like that can cause discomfort or ear damage.

Additional Features

Key finders can be simple or enhanced with a variety of extras. In addition to a loud alarm, some key finders offer one or more of the following features:

  • Seamless app integration is one of the benefits of buying a Bluetooth key finder. But the apps themselves vary greatly in quality and user-friendliness. Pay attention to customer ratings and reviews, where honest feedback is provided. Tile brand trackers have gone through various improvements over the years, so their app is one of the most sophisticated and user-friendly, and is compatible with both Apple and Android phones.
  • Battery life affects all key finders, regardless of whether they use Bluetooth or RF technology. Some brands provide additional batteries, which can be helpful to keep your finder going.
  • A built-in LED flashlight can help you track down items at night, in dark corners, or between cushions. RF key trackers operated by remote transmitters often contain an LED light (in the transmitter itself) for just such a purpose. Once you push the button to sound the alarm, use the transmitter as a flashlight to find your keys and other misplaced items.
  • A selfie button allows you to take photos at a distance. Some key finders can be paired with your phone’s camera.
